Abstract

Low water liquid beverage concentrates and methods for making the concentrates are provided herein. The concentrates include a high coffee and/or tea solids content and total solids content. The amounts of water, total solids, and coffee and/or tea solids are effective to provide a low water beverage concentrate having a pH between about 3.0 to about 6.0. In some approaches, the pH of the low water beverage concentrate changes fewer than about 0.5 pH units after at least three months storage at 70 F in a closed container. The low water beverage concentrates provide a desired flavor profile with little or no flavor degradation after storage at 70 F in a closed container for at least about three months. Methods for making the low water beverage concentrates are also provided.

First claim

What is claimed is:

1. A low water liquid beverage concentrate comprising:
about 15 to about 40 percent total water by weight of the concentrate;
about 20 to about 80 percent low water liquid by weight of the concentrate; and
about 5 to about 60 percent coffee and/or tea solids by weight of the concentrate,
the amount of water, low water liquid, and coffee and/or tea solids effective to provide a low water liquid beverage concentrate having a pH between about 3.0 to about 6.0, the pH of the low water liquid beverage concentrate changing less than about 0.5 pH units after 12 months storage at 70° F. in a closed container,
wherein the low water liquid comprises at least one of fructose syrup, glucose syrup, sucrose syrup, lactose syrup, carbohydrate syrup, honey, agave syrup, monosaccharide, disaccharide, and combinations thereof.

2. The low water liquid beverage concentrate of claim 1 , wherein the concentrate comprises about 20 to about 70 percent low water liquid by weight of the concentrate.

3. The low water liquid beverage concentrate of claim 1 , wherein the low water liquid further comprises at least one non-aqueous liquid of the group consisting of sugar alcohol, glycerol, propylene glycol, 1,3-propanediol, ethanol, triacetin, ethyl acetate, benzyl alcohol, vegetable oil, vitamin oil, and isopropanol.

4. The low water liquid beverage concentrate of claim 1 , wherein the coffee and/or tea solids comprise at least one of the group consisting of freeze-dried coffee, spray-dried coffee, spray-dried tea, freeze dried tea, roast coffee, instant coffee powder, instant tea powder, roasted ground coffee beans, cold brewed tea solids, cold brewed coffee solids, micro grind coffee, agglomerated coffee solids, coffee extract, tea extract, botanical extract, ground tea leaves, and combinations thereof.

5. The low water liquid beverage concentrate of claim 1 , wherein the coffee and/or tea solids comprise spray-dried coffee.

6. The low water liquid beverage concentrate of claim 1 , wherein the concentrate comprises about 10 to about 40 percent coffee and/or tea solids.

7. The low water liquid beverage concentrate of claim 1 , wherein the concentrate comprises about 10 to about 30 percent coffee and/or tea solids by weight of the concentrate.

8. The low water liquid beverage concentrate of claim 1 , wherein the concentrate includes about 15 to about 70 percent total solids by weight of the concentrate.

9. The low water liquid beverage concentrate of claim 1 , wherein the concentrate further comprises up to about 5 percent high intensity, non-nutritive sweetener solids by weight of the concentrate.

10. The low water liquid beverage concentrate of claim 1 , wherein the concentrate has a total water content of about 25 to about 40 percent by weight of the concentrate.

11. A low water liquid beverage concentrate comprising:
about 25 percent to about 60 percent total water by weight of the concentrate;
about 20 to about 70 percent low water liquid, the low water liquid comprising at least one of fructose syrup, glucose syrup, sucrose syrup, lactose syrup, carbohydrate syrup, honey, agave syrup, monosaccharide, disaccharide, and combinations thereof, and the low water liquid also comprising at least one of sugar alcohol, glycerol, propylene glycol, 1,3-propanediol, ethanol, triacetin, ethyl acetate, benzyl alcohol, vegetable oil, vitamin oil, and isopropanol;
about 15 to about 70 percent total solids by weight of the concentrate; and
about 5 to about 60 percent coffee and/or tea solids by weight of the concentrate,
the amount of water, total solids, and coffee and/or tea solids effective to provide a low water liquid beverage concentrate having a water activity of about 0.6 to about 0.95 and a pH between about 3.0 to about 6.0, and the amount of water, total solids, and coffee and/or tea solids effective to prevent the pH of the low water liquid beverage concentrate from changing more than about 0.5 pH units after 12 months storage at 70° F. in a closed container.

12. The low water liquid beverage concentrate of claim 11 , wherein the coffee and/or tea solids comprise spray-dried coffee.

13. The low water liquid beverage concentrate of claim 11 , wherein the concentrate comprises about 10 to about 40 percent coffee and/or tea solids by weight of the concentrate.

14. The low water liquid beverage concentrate of claim 11 , wherein the concentrate comprises about 10 to about 30 percent coffee and/or tea solids by weight of the concentrate.

15. The low water liquid beverage concentrate of claim 11 , wherein the concentrate has a total solids content of about 30 to about 70 percent by weight of the concentrate.

16. The low water liquid beverage concentrate of claim 11 , wherein the concentrate includes coffee solids and does not include tea solids.

17. The low water liquid beverage concentrate of claim 11 , wherein the concentrate includes water, total solids, and coffee and/or tea solids in amounts effective to provide the concentrate with a pH that changes fewer than about 0.1 pH units.

18. The low water liquid beverage concentrate according to claim 11 , wherein the concentrate has a water activity of about 0.65 to about 0.85 and a pH of about 4.5 to about 5.5, wherein the pH is measured within one day of the beverage concentrate being produced and stored in a closed container at 70° F.

19. A method of preparing a low water liquid beverage concentrate, the method comprising:
providing a pre-concentrate comprising coffee and/or tea solids in water; and
mixing about 10 to about 75 percent by weight pre-concentrate by weight of the low water liquid beverage concentrate with about 25 to about 90 percent by weight low water liquid by weight of the low water concentrate,
the amount of pre-concentrate and low water liquid effective to provide a low water liquid beverage concentrate having about 15 to about 40 percent total water, a pH between about 3.0 to about 6.0, and the pH of the low water liquid beverage concentrate changing fewer than about 0.5 pH units after 3 months storage at 70° F. in a closed container,
the low water liquid comprising at least one of fructose syrup, glucose syrup, sucrose syrup, lactose syrup, carbohydrate syrup, honey, agave syrup, monosaccharide, disaccharide, and combinations thereof, and
the low water liquid also comprising at least one of sugar alcohol, glycerol, propylene glycol, 1,3-propanediol, ethanol, triacetin, ethyl acetate, benzyl alcohol, vegetable oil, vitamin oil, and isopropanol.

20. The method of claim 19 , wherein the low water liquid beverage concentrate includes about 5 to about 60 percent coffee and/or tea solids by weight of the liquid beverage concentrate.

21. The method of claim 19 , wherein the concentrate includes about 15 to about 70 percent by weight total solids.

22. The method of claim 19 , wherein the low water liquid beverage concentrate has a total water content of about 25 to about 40 percent by weight of the concentrate.
